Locally Confined Modality Fusion Network With a Global Perspective for Multimodal Human Affective Computing

Mai, Sijie, Xing, Songlong, Hu, Haifeng·2020·IEEE Transactions on Multimedia

Abstract

In this paper, we propose a novel multimodal fusion framework, called the locally confined modality fusion network (LMFN), that contains a bidirectional multiconnected LSTM (BM-LSTM) to address the multimodal human affective computing problem. In the LMFN, we introduce a generic fusion structure that explores both local and global fusion to obtain an integral comprehension of information. Specifically, we partition the feature vector corresponding to each modality into multiple segments and learn every local interaction through a tensor fusion procedure. Global interaction is then modeled by learning the dependence between local tensors via an originally designed BM-LSTM architecture, establishing a direct connection of cells and states of local tensors that are several time steps apart. With the LMFN, we achieve advantages over other methods in the following aspects: 1) local interactions are successfully modeled using a feasible vector segmentation procedure that can explore cross-modal dynamics in a more specialized manner; 2) global interactions are modeled to obtain an integral view of multimodal information using BM-LSTM, which guarantees an adequate flow of information; and 3) our general fusion structure is highly extendable by applying other local and global fusion methods. Experiments show that the LMFN yields state-of-the-art results. Moreover, the LMFN achieves higher efficiency compared to other models by applying the outer product as the fusion method.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
